Windows 10 is launching on Wednesday, and it’s everything a PC operating system should be: familiar, beautiful, easy to use and helpful in unexpected ways. The best part: it’s a free upgrade for just about everyone currently running Windows 7 and 8.
Microsoft (More, Tech30) took great pains to get Windows 10 right,opening up a preview version of the software to the public, asking for feedback and making dozens of changes as a result. That’s why Microsoft is confident you’ll love Windows 10. The company expects that 1 billion devices will run the new operating system in the next two or three years.
